英文摘要	本文合成了掺铝富锂材料Li1.2Mn0.543Co0.078Ni0.155Al0.030O2，并使用扫描电镜（SEM）、粉末X射线衍射（XRD）、电感耦合等离子体原子发射光谱（ICP-AES）和拉曼散射光谱（Raman）等观察表征富锂和掺铝富锂材料. 结果表明，共沉淀法合成掺铝富锂材料，具有R-3m空间群结构，Al元素进入晶格，未单独成相. 电化学性能和非现场XRD测试结果表明，4%（by mole）掺铝富锂电极100周期循环容量保持率83.7%，Al元素掺杂有利于容量的释放，增强了电极富锂材料的结构稳定性，提高了循环性能.; The Al-doped 0.5Li2MnO3·0.5Li(Mn0.4Co0.2Ni0.4)O2 compounds were successfully synthesized as cathode materials for lithium-ion batteries. The pristine and Al-doped materials were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), inductively coupled plasma-atomic emission spectrometry (ICP-AES) and laser Raman spectroscopy. The results indicated that all the prepared materials were indexed as a hexagonal structure with R-3m space group, and Al element had been introduced into lattice. When cycled at 180 mA·g-1 (1 C-rate), the capacity retention of 4% (by mole) Al-doped 0.5Li2MnO3·0.5Li(Mn0.4Co0.2Ni0.4)O2 electrode was as high as 83.7% after 100 cycles. The Al-doped materials could enhance the structural stability of electrodes, which contributes to high stabilized performance of cathode material for lithium ion batteries.; 国家重点基础研究发展计划项目（No. 2007CB935603）资助; 作者联系地址：厦门大学化学化工学院，福建厦门 361005; Author's Address: College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, Fujian, China; 通讯作者E-mail：zcwang@xmu.edu.cn
